Join Mark Thomas for an in-depth discussion in this video The four phases of Release and Deployment Management, part of Cert Prep: ITIL Foundations.
- Okay, within release and deployment management, still in transition, four primary phases that we go through in a release. And they're release and deployment planning, build test, deploy it, review and close. Seems pretty easy, right? But there's a lot of moving parts here we need to make sure that we're aware of. So first, let's start with the deployment planning. So this the planning phase of that deployment within transition, so remember it begins with change management authorization, we hid that back in change. Now remember change is the approval authority for us, so change says "you have the authority now "to go into release and deployment planning" and when we are finished with that planning, we get the authorization from change managment to create the release, so change is actually controlling how we walk through and doing the appropriate approvals on these things.
So, in planning, making sure that we have the test plans understood, what the pass/fail or what the criteria will be for moving through the four phases, the logistics, the planning of each one of these things, financial stuff, those type of things are what we're doing on the planning side. Change says, "you are now authorized "to go in and to create the release." So now we go into what's called build and test. Remember it begins with change authorization and it ends with change authorization to put this into that thing called the DML, the definitive media library that we talked about.
So, this is where it's built, tested and its stored in that DML. And so, sometimes we may be using suppliers for this, we may be using internal for this and this is where we also may be doing some type of iterative approach build, test, build, test based on our release packages and release units. So, change says, "put it in the DML, "we give you authorization." It goes to the DML and we use that DML as kind of that staging piece to move onto the deployment side and the deployment, change authorization to deploy the release, that release then goes through deployment, through whatever policies and procedures we have on that deployment, do we have a release window? Do we have multiple release windows in which we are deploying those release packages and release units in a controlled manner.
So, when it's complete we hand that over to service operation with early life support. That's that early life support that we talked about in the previous session. Now, once that deployment is complete, a couple of things I want to make I hit on this. That we have to make sure organizational readiness, service acceptance is done and that we are also doing the knowledge transfer that we have to do as a part of that deployment piece, so we can't forget those things in there. So, we review and close.
When we review and close we have review and then close of the deployment, capture the feedback, do the lessons learned, the post-implementation review that might take place with that. Then also do the service transition, which is a formal review on service transition to ensure that we've completed the documentation, the information, the transfer and all those pieces that come along with that. Four big phases, plan it, build/test, deploy it, review and close, let's take a look at another perspective of this and give you a little bit more detail.
On this next slide you see the relationship now we have with change management and the activities we might have or the phases of release and deployment. So you see change management at the top, notice authorization for release planning, authorization for build and test, authorization to check into the DML we've talked about those and there may be authorization for the separate deployments that we might have and then a post-implementation review. That post-implementation review is done by the release manager.
Well, when we do the authorize release planning, release and deployment processes conducting their activities to do that. Once it goes into the DML, now we can pull it from the DML for the deployment, the transfer or the retirement of each one of those, the review and close is the last piece. Now, remeber, there might be early life support that we talked about which might be part of that final release. So, release and deployment management. Build, test and deploy into the live environment.
